I would also suggest, grouped by type series for LG and LR, either by Traciela or PowerScore.

Yes you'll have plenty of practice questions with what you have, but I've dramatically improved by just drilling one type of questions. Tip: if you buy LG Traciela PDF documents from their website and you can print 3 copies collated to have 3 of the same question replicated 3 times in a row and practice a la Pithypike method.
